Babies create massive stress.
Baby related stress triggers a massive craving for chocolate.
Case in Point -
Prior to baby - I worked a high stress job and thrived on it. I get really bored and unmotivated without work stress. Did not led to chocolate or junk food craving.
During pregnancy - continued working high stress job and somehow found rhythm that kept me mentally relaxed but balanced to handle work stress - did not crave chocolate - in fact avoided it out of lack of interest.
Post pregnancy - long spell with baby of repeated eating, diapering, putting to bed for 15 minutes while making mad dash for lunch or loo typically has me scrambling for chocolate! Today, I worked in office for 3 hours in back to back meetings discussing all manner of stress related work issues, downsizing, price problems, job reviews, etc. Not fun stuff! Never once felt need to eat chocolate. I come home to give husband a break while he runs off to teach a class, 3 hours in and I'm scrambling for chocolate and a glass of milk.
I don't understand it but I blame it all on baby.
